Description
Die Erfindung betrifft eine Verstärkerkapsel mit Oktogenkristallen für Geschosse zur Detonationseinleitung oder zur Detonationsübertragung.The invention relates to an amplifier capsule with octogen crystals for projectiles for detonation initiation or for detonation transmission.
Es hat sich gezeigt, daß die bekannten Verstärkerkapseln dieser Art nicht alle gleich zuverlässig initiierfähig sind.It has been shown that the known amplifier capsules of this type are not all equally reliable and capable of being initiated.
Die vorliegende Erfindung bezweckt, die Initiierfähigkeit dieser Verstärkerkapssln zu verbessern und ihre ' Störanfälligkeit zu vermindern.The present invention aims at initiating ability to improve these amplifier capsules and to reduce their susceptibility to failure.
Die erfindungsgemäße Verstärkerkapsel ist dadurch gekennzeichnet, daß die Oktogenkristalle größer als 75 μηι und kleiner als 150 μπι sind, daß das Längen-Durchmesser- Verhätnis der Kristalle 3:1 ist, und daß die Kanten der Kristalle unbeschädigt sind.The amplifier capsule according to the invention is characterized in that the octogen crystals are larger than 75 μηι and smaller than 150 μπι are that the length-diameter The ratio of the crystals is 3: 1 and that the edges of the crystals are undamaged.
Vorzugsweise besitzt das Oktogen am einen Ende der Verstärkerkapsel eine größere Dichte als am anderen Ende, die Dichte nimmt stufenweise ab und ist am Ende so klein, daß die Kristalle ganz bleiben.The octogene preferably has a greater density at one end of the amplifier capsule than at the other At the end, the density gradually decreases and at the end it is so small that the crystals remain intact.
Vorzugsweise besitzen mindestens 30% der Kristalle des Oktogens die genannten Eigenschaften.Preferably at least 30% of the crystals of the octogen have the properties mentioned.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung der genannten Verstärkerkapsel. Dieses Verfahren zur Herstellung der Verstärkerkapsel ist dadurch gekennzeichnet, daß durch Naß-Sieben die Menge der bevorzugten Kristalle in einer Mischung verschiedenartiger Oktogenkristalle angereichert wird.The invention also relates to a method for producing said amplifier capsule. This Process for the production of the amplifier capsule is characterized in that the wet sieving Amount of preferred crystals is enriched in a mixture of different octogen crystals.
Versuche haben bestätigt, daß die Initiierfähigkeit des Oktogens von der Form und der Größe der Kristalle abhängig ist, wobei diese möglichst unbeschädigt sein sollen.Experiments have confirmed that the initiating ability of the Octogen depends on the shape and size of the crystals, and these should be as undamaged as possible should.
Ein Ausfuhrungsbeispiel der erfindungsgemäßen Verstärkerkapsel ist im folgenden an Hand der Zeichnung ausführlich beschrieben. Es zeigtAn exemplary embodiment of the amplifier capsule according to the invention is given below with reference to the Drawing described in detail. It shows
F i g. 1 und 2 Oktogenkristalle in schaubildlicher Darstellung,F i g. 1 and 2 octagonal crystals in a diagrammatic representation,
Fig.3 bis 6 verschiedene Verfahrensschritte zur Herstellung der Verstärkerkapsel,3 to 6 different process steps for the production of the amplifier capsule,
und kleiner als 150 μπι und sein Längen-Durchmesser Verhältnis ist ca. 3:1.and smaller than 150 μπι and its length diameter Ratio is around 3: 1.
Demgegenüber ist der im gleichen Maßstab in F i g. 2 dargestellte Kristall größer als 150 μιη außerdem besitzt er nicht das gewünschte Längen-Durchmesser-Verhältnis von ca. 3:1, und somit auch nicht die erforderliche InitiierfähigkeitIn contrast, the one on the same scale in FIG. 2 also has a crystal larger than 150 μm it does not have the desired length / diameter ratio of approx. 3: 1, and thus also not the required one Initiation ability
Wesentlich für eine gute Initiierfähigkeit ist, daß die Kristalle nicht beschädigt sind. Durch Sieben, insbesondere Naß-Sieben, lassen sich zwar zu große und zu kleine Kristalle ausscheiden. Schwieriger ist die Aussortierung der Kristalle nach ihrer Form. Wie jedoch die Betrachtung der Kristalle durch das Mikroskop zeigt, sind die länglichen Kristalle kleiner als die eher kugelförmigen Kristalle, so daß durch ein Sieb-Verfahren eine Anreicherung der länglichen Kristalle möglich ist Die Kristalle werden im wesentlichen durch große Drücke beschädigt Wenn möglichst alle Kristalle unbeschädigt sein sollen, dürfen die Drücke beim Einfüllen in die Kapsel gewisse Werte nicht überschreiten.It is essential for a good ability to initiate that the Crystals are not damaged. By seven, in particular Wet sieving allows crystals that are too large and too small to be separated out. That is more difficult Sorting out the crystals according to their shape. How, however, the observation of the crystals through the Microscope shows the elongated crystals are smaller than the more spherical crystals, so that through a Sieve method an enrichment of the elongated crystals is possible The crystals are essentially damaged by high pressures If all crystals are to be undamaged, the Do not exceed certain values when filling the capsule.
Gemäß F i g. 3 wird eine Menge von ca. 140 mg Oktogen unter einem Druck von ca. 13 bar in eine Hülse 10 mit Boden U mit Hilfe eines Stempels 12 hineingepreßtAccording to FIG. 3 a quantity of approx. 140 mg octogen is put into a sleeve under a pressure of approx. 13 bar 10 with the bottom U pressed in with the aid of a punch 12
Gemäß F i g. 4 wird anschließend eine weitere Menge von wiederum ca. 140 mg Oktogen unter einem kleineren Druck von ca. 7 bar in die selbe Hülse 10 hineingepreßtAccording to FIG. 4 is then another amount of again about 140 mg octogen under one a smaller pressure of approx. 7 bar is pressed into the same sleeve 10
Gemäß F i g. 5 wird schließlich eine letzte Menge von nochmals ca. 140 mg Oktogen unter einem noch kleineren Druck von ca. 3 bar in die Hülse 10 hineingepreßtAccording to FIG. 5 is finally a final amount of about 140 mg octogen under a still a smaller pressure of approx. 3 bar is pressed into the sleeve 10
Gemäß F i g. 6 wird die Hülse 10 durch einen Deckel 13 verschlossen und der obere Rand der Hülse 10 wird umgebördelt, wobei ein Druck von ca. 21 bar erforderlich istAccording to FIG. 6, the sleeve 10 is closed by a cover 13 and the upper edge of the sleeve 10 is flanged, with a pressure of approx. 21 bar required is

Durch sorgfältige Siebverfahren wird man versuchen, die bevorzugten Kristallformen in möglichst großer Reinheit zu erhalten. Durch die niedrigeren Drücke bei der zweiten und dritten Menge gemäß F i g. 4 und 5 sind die Kristalle weniger beschädigt und die InitiierfähigkeitCareful sieving procedures will try to obtain the preferred crystal forms in as large a size as possible To maintain purity. Due to the lower pressures in the second and third quantity according to FIG. 4 and 5 are the crystals are less damaged and the ability to initiate
ist daher größer. Diese Initiierfähigkeit läßt sich mit speziellen Testverfahren prüfen. Aus dem Diagramm gemäß F i g. 7 ist ersichtlich, daß die Initiierfähigkeit von der Korngröße abhängig ist Bei dem Testverfahren werden zwischen eine Zündkapsel und die zu prüfende Verstärkerkapsel ein, zwei oder drei Aluminnimplättchen gelegt Bei guter Initiierfähigkeit kann die Verstärkerkapsel noch bei drei Plättchen gezündet werden, bei schlechter Initäerfähigkeit verhindert schon ein Plättchen die Zündung der Verstärkerladung.is therefore larger. This ability to initiate can be checked with special test methods. From the diagram according to FIG. 7 it can be seen that the initiating ability of the grain size is dependent. During the test procedure, between an ignition capsule and the one to be tested Amplifier capsule one, two or three aluminum platelets laid If the initiation ability is good, the amplifier capsule can still be ignited with three platelets If the initiation ability is poor, a small plate prevents the booster charge from igniting.
Durch ein Naß-Sieb-Verfahren ist es möglich, die Menge der Kristalle der Größe zwischen 75— 150μπι die ein Längen-Durchmesser-Verhältnis von 3:1 aufweisen, in einer Mischung verschiedenartiger Oktogenkristalle auf mindestens 30% anzureichern.Using a wet sieve process, it is possible to reduce the amount of crystals between 75 and 150 μm in size which has a length-to-diameter ratio of 3: 1 have to enrich in a mixture of different octogen crystals to at least 30%.
